9 Claims. (Cl. 72--101) The invention relates to wall plates, and more particularly it relates to wall plates providing anchor members for brick lining walls for furnaces, ash pits and the like.

The use of wall plates for this purpose is wellknown, but such plates as heretofore constructed are not adapted for use with brick walls of standard construction, since their anchorage requires that some or all of the brick be of special construction or that they be arranged in some special manner.

It is an object of the invention to provide wall plates of the kind described having anchor members so arranged and constructed that brick of standard sizes and construction may be laid perpendicular to the wall plate to form a wall anchored to the plates and providing a smooth exposed surface completely concealing the anchor members. This desirable result is accomplished by providing wall plates adapted to be assembled to form a wall either vertical or inclined and having anchor members proj ectlng at right angles from the face of the plate adjacent the wall. The anchor members are arranged in horizontal and vertical rows and so constructed as to occupy the mortar spaces adjacent the contiguous ends of the brick with each anchor member providing lateral projections upon which the ends of the contiguous brick are positioned. The anchor members are also arranged in vertical rows in such a manner that each horizontal layer of brick breaks joints with the brick immediately above and below.

Another object of the invention is the provision of improved wall plates of the kind described, adapted to form a unit of an assembly provlding a backing for a brick wall, said plates each providing a plurality of projecting anchor members so arranged that their outer ends occupy the mortar spaces at the ends of the brick and are concealed by the mortar, the inner ends of the anchor members being so constructed as to provide spacers limiting the proximity of the brick to the plates, thereby providing an air space between the brick wall and the assembled plates.

Another object of the invention is the provision of a wall plate providing a plurality of anchor members so constructed as to interlock with the mortar joints of a brick wall built thereabout and to provide keys adapted to prevent relative movement of the wall and the plate after the mortar is set.

Still another object of the invention is the provision of a wall plate providing a plurality of improved anchor members of the kind described, which is durable, adapted to be economically manufactured, and is satisfactory for its intended purpose. Many other objects and advantages of the construction herein shown and described will 5 be obvious to those skilled in the art from the disclosure herein given.

To this end my invention consists in the novel construction arrangement and combination of parts herein shown and described, and more par- 10 ticularly pointed out in the claims.

In the drawings, wherein like reference characters indicate like or corresponding parts:

Fig. 1 is a perspective view of a fragmentary portion of a wall built about and concealing the l5 anchor members of a plate embodying the principles of the invention;

Fig. 2 is an elevational view of a fragmentary portion of an assembly of wall plates embodying the principles of the invention;

Fig. 4 is a View along the line 4 4 of Fig. 2, drawn to a larger scale Figs. 5, 6, 7, and 8 are respectively plan views 25 of modiiied forms of anchor bars embodying the principles of the invention; and

Fig. 9 is a side elevational view of the anchor bar shown in Fig. 6.

Referring now more particularly to the draw- 30 ings, the numeral I0 generally designates a plate construction of any suitable material, preferably cast iron or steel and of any desired width and height adapting it as a unit of a wall assembly. Fig. 2 shows in elevation one complete plate I0, 35 and fragmentary portions of contiguous plates providing anchor bars arranged in the positions shown. The assembly comprises a. plurality of rows of superimposed plates l0, the height and number of rows being variable in accordance with o the required dimensions of a brick wall built about and covering the anchor bars projecting from the plates. All of the plates I0 are shown as of uniform length and width but such dimensions may be varied if desired to adapt the assembly "5 of plates to the dimensions of the brick wall for which the plates provide a backing.

Each plate I0 has an outwardly projecting flange Il provided with apertures I2, positioned to register with corresponding apertures in the flanges of adjacent plates and adapted to receive bolts or rods for connecting the plates to form an assembly providing a wall of the height and width required for any particular installation. 'I'he u plate assembly is shown as providing a vertical wall but may be inclined to the vertical if desired, and the upper flanges of the top plates may be fastened to beams or other members not shown. A plurality of triangular shaped web members I3, connecting the plates I0 with the fianges I I. reinforce the plates and prevent warping or cracking. The plates I0 are further reinforced by transversely extending members I4, as shown in Figs. 2 and 3.

Ihe plates I0 are provided with a plurality of anchor bars I5a and I5b projecting perpendicularly from the plates and so positioned as to form vertical and horizontal rows when the plates are assembled as shown in Fig. 2. The anchor bars are similar but for convenience in describing their arrangement certain of the bars are designated by numerals I5a and the others by numerals I5b. The anchor bars are shown as of inverted T- shaped cross section, and each is connected with the plate ID by a boss I6.

The anchor bars I5a and I5b on the various plates IU comprising the assembly are so arranged that the bars are adapted to occupy the mortar spaces adjacent the ends of the brick when laid in stretching bond with the brick comprising each horizontal layer breaking joints with brick in each layer next above and below. For this purpose the bars I5a and I5b are so arranged on the plates III as to provide vertical and horizontal rows. The bars I5a are arranged in vertical rows and are so spaced in the rows as to occupy the mortar spaces adjacent the ends of alternate horizontal layers of brick. The bars I5b are also A arranged in vertical rows intermediate the vertical rows of bars I5a and are so positioned as to occupy the mortar spaces adjacent the ends of the brick, in the horizontal rows intermediate those in which the bars I5a are positioned.

The lower iiat portions Ill of the anchor bars preferably have a thickness slightly less than that of the mortar spaces between the horizontal layers of brick, and the stem portions I8 o! the anchor bars have a thickness slightly less than that of the vertical mortar spaces between the ends of the contiguous brick. The described construction and arrangement of the anchor bars is such that standard rectangular brick may be utilized to build a wall with brick arranged in stretching bond and having alternate horizontal layers breaking joints by positioning the brick with their ends resting upon the laterally projecting portions or members I'I. A wall so built will conceal the anchor bars since the bars stop short of the exposed face of the brick sumciently to be completely hidden by the mortar joints.

It is desirable to provide an air insulating space between plates I0 and the brick wall to minimize the range of temperatures to which the plates are subjected and for this purpose I have provided a boss I6 at the base of each anchor bar. The bosses I6 are adapted as guides for laying the brick and make certain that an air insulating space will be provided by the plates I0 and the brick. By laying the brick with their inner edges in contact with the bosses I6 the insulated space will be uniformly of the thickness of the bosses and the exposed surface of the brick will be in alignment. The width of the members I'I and the height of the stems I8 increase outwardly from the plates I0 thereby providing keys adapted to lock the brick in the mortar and prevent their movement relative to the plates after the mortar has set.

Figs. 5 to 9 illustrate modied forms of anchor addition of a stem member 2U shown in elevation bars adapted to be embedded in the mortar spaces of brick walls of the kind described. Fig. 5 illustrates the anchor bars as comprising a ilat plate I9 adapted to occupy the mortar space between horizontal layers oi brick and each con- 5 nected with the plate I0 by a spacer boss I6. The edges of the plates I9 are of irregular con` guration for interlocking with the mortar. Fig.

6, is of the same construction as Fig. 5, with the 10 in Fig. 9 as increasingv in depth outwardly from the plate I0. If desired the stem 20 may be made of substantially uniform depth with its upper edge of irregular configuration to interlock with the mortar.

Fig. '7 illustrates another form of anchor bar comprising a flat plate 2| having lateral projections 22 at its i'ree end adapted to interlock with the horizontal mortar joints. The construction shown in Fig. 8 is similar to that shown in Fig. 7 and in addition provides a stem member 20 shown in elevation in Fig. 9.

Thus it will be seen that I have provided an improved wall plate construction and assembly comprising improved anchor bars adapted to occupy the mortar spaces of a lining wall built of brick of standard construction without any modiflcation of sizes or shapes of the brick. The construction is also adapted for use with either vertical or inclined walls and insures the provision of an air insulating space tending to minimize the warping of the plates which otherwise results from the high temperatures to which they are exposed.

Having thus described my invention, it is ob- 35 vious that various immaterial modications may be made in the same without departing from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction. arrangement and combination of parts herein shown and described or uses mentioned.
